Supersymmetric quantum criticality supported by baryonic charges

In the context of the AdS(4) x Q(111) solution of D = 11 supergravity we construct supersymmetric zero temperature black brane solutions that interpolate between AdS(4) in the UV and AdS(2) x R-2 in the IR. The dual N = 2 SCFT has a U(1)(2) baryonic symmetry and the solutions carry electric charge with respect to one of the U(1) factors and magnetic charge with respect to the other. The solutions describe stable zero temperature ground states of the deformed SCFT which have finite entropy density. We also construct analogous supersymmetric solutions that flow to AdS(2) x S-2 and to AdS(2) x H-2/Gamma in the IR which, in addition, carry magnetic R-symmetry charge similar to other known wrapped brane solutions.
